What it does

Copying Flags Across Projects is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Copy a feature flag from one PostHog project to one or more target projects in the same organization. Use when the user wants to duplicate a flag, promote a flag from staging to production, sync flags across projects, or replicate a flag configuration in a different workspace. Covers cohort remapping, scheduled-change handling, encrypted payloads, and the safe defaults (disabled in target, no scheduled changes).

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with PostHog. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…

When your agent uses it

  • The user wants to duplicate a flag
  • Promote a flag from staging to production
  • Sync flags across projects
  • Replicate a flag configuration in a different workspace

Example prompts

  • “/copying-flags-across-projects”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Resolve the source flag
  2. Resolve target project ids
  3. Preview the source flag and its dependencies
  4. Confirm copy options
  5. Execute the copy
  6. Report per-target outcome

What it can do on your machine

Read from SKILL.md and the folder at commit 812e5c6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Copying Flags Across Projects loads about 2.2k tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 1,222 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~111
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,222 words (~2,243 tokens).

“This skill guides you through duplicating a feature flag from a source project into one or more target projects within the same PostHog organization.”
